BINDER.

SPECIFICATION forming* part Of Letters Patent NO. 787,368, (lated April 18, 1905.

Application filed February 24, 1902. Serial No. 95,218.

Ie it known that I, Au'ruUeV. Finsltnv, a citizen of the L'nited States, residing at Ohicago, in the county of (-Ook and State of Illinois. have invented certain new and useful .lmprovements in Binders, of which the following is a full. clear. and exactspecitication.

)Iy invention relation thatclass of binders employed for holding loose leaves or sheets and usually comprising a pairof covers having hinged portions in one of which one or more impaling-pins are planted and passed through registering perforations in the leaves and the other cover, combined with means for securing the latter cover firmly to the impalingpins, and thereby holding' it snugly against the leaves: and my invention has for one of its important objects to provide an impaliugpin which shall be composed of detachable sections, so that the length thereof may be varied to suit the thickness of the leaves between the covers.

Another object of my invention is to provide improved and simple means for clamping one of the covers down against the leaves.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of pa rts by which the said objects and certain other objects hereii'iafter appearing are attained` all as fully described with reference lo the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure I is a pei'- spective view of a binderembodying my improvements. Fig. 2 is an enlarged detail sectional view of a part of one of the covers, taken on the line 2 2, Fig. (i. Fig. i. isa sectional view taken on the line 2%, Fig. 4, the covering or bindingl of the cover being omitted. Fig. t is an enlarged detail section taken on the line J., Fig` I. Fig. 5 is a transverse section taken on the line 5, Fig. :2. Fig. t3 is a similar section taken on the line 6, Fig. L). Fig. T is a longitudinal sectional view of my improved impaling-pin. Fig. 8 is a similar view thereof, showingthe pin eX- tended in length for a thicker book or block of leaves. Fig. J isa detail longitudinal se tional view of one of the sections of the iml i l i l i paling-pin, and Fig. It) is a similar view of another one of such sections.

I Q are the covers proper, which are suitably hinged in the usual manner to strips 3 4, extending alongthe edge thereof` and through which latter it is customary to pass the impaling-pins. The covers proper` 1 2, may be composed of pastoboard or any other-suitable material provided with a covering 5, which may be also carried around the strips 3 and serve to constitute the hinge between the strips 3 and the covers proper. These strips 3 are each composed of a flattened tube 6, whose ends are closed by caps T S. The lower threaded ends t) of the iinpaling-pins are passed through suitable perforations in the tubes 6 and secured in blocks It), forced into and held by the lower one of the tubes ti, as shown in Figs. 3 and 4f, each of the blocks It) filling-the cross-section of the tube. The upper tube. Vforms a` guide and housingfor the clamping-blocks` which grip the impaling-pins, and thereby lock the strip 3 lirmly against the pile of leaves. These clamping-blocks are shown at l1 l2, and they are provided in their outer sides with semicircular notches 13 14, which are adapted to i'it around the impaling-pins and when the blocks are wedged apart to pinch the pins with suliicient force to prevent the upper strip 3 froln being raised. This wedging action of the blocks I1 I2 is produced by a screw I5, threaded in the block 12 and having` its extremity swiveled in the block 11. the latter being provided with a socket extending' part way through it, in which the end of the screw-rod l5 inserted and held by a crosspin or key I6 passing through the block Il and engaging ina peripheral groove I7 in the rod, The opposite end of the screw may be held in place by a pair of cross-bars IS, riveted in opposite sides of tube (3 and passing' on either side of the screw. The outer extremity of the screw is provided with a keypost IJ, arranged opposite a keyhole 2O in the cap S. By the means described it will be seen that when the screw l5 is turned in one direction the gripping-blocks Il I2 will be forced apart for clamping the impalingpins and when turned in the opposite direction theirn- IOC paling-pins will be released to permit the upper cover-strip 3 to be raised for inserting or removing the leaves, the tube 6 constituting means for holding' and guiding the blocks 11 12 in these movements.

The impaling-pins (one or more of which may be used, two being shown) are each composed of the detachable sections, as shown in Figs. 7 to l0, inclusive. The lower section, which carries the threaded end 9, is composed of a tube 21, in which is firmly secured an internally-threaded nut 22. In this nut 22 is screwed thelower end of a short rod 23, which passes through and is virtuall y a part of a sleeve 24, around which is secured a collar 25, much shorter than and arranged at about the midlength of the sleeve 24, as more clearly shown in Fig. 9, so that the ends of the collar 25 will form abutting shoulders for the upper end of the tube 21 and the lower end of a tube 26, which fits over the upper end of tube 24 and in which is secured a nut 27, threaded on the upper end of rod 23. Into the upper end of nut 27 is threaded the lower end of a rod 23X, belonging to another one of the sections, like that shown in Fig. 9, 24X being the part corresponding to 24 and 25 the collar corresponding to the collar 25. This pin is built up in this manner by means of' the described sections until the desired height is attained, and the upper end is finished off by means of a cap 28, fitted down over the end of sleeve 24 or 24X and `threaded on the upper end of rod 23 or 23X, the cap 28 being provided with a lnurled head 29, if desired, for preventing the upper strip 3 from being accidentally displaced and also affording means for unscrewing the cap 28.

The numbers 23 24 25 constitute the male section, Whose tenons 24 are received in the socket ends of the female sections comprised by members 26 27, and by these means it will be seen a post or pin of the desired height may be built up, the base-sections 21 22 and cap-section 29 fitting either end of any one of the male sections.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, iss- 1. In a binder the combination with the cover, of an impaling-pin comprising a plurality of male sections, a plurality of female sections, a base-section and a cap-section; each of said male sections comprising' a shoulder at its largest diameter with a tenon at each end thereof and a male screw smaller than the tenons projecting from each of the latter, said female sections each consisting of a socket at each end for receiving either of said tenons and a female screw at the inner end of each of said sockets for receiving' either of said male screws, said base-section comprising a female screw for receiving either of said male screws and means for attaching it to the cover, and said cap-section comprising a female screw for receiving either of said male screws.

2. In a binder, the combination of a hollow cover member, impaling-pins passing therethrough, two grip-blocks arranged loosely in and guided by said hollow cover member, and a screw swiveled in and immovable longitudinally with relation to one of said blocks and threaded in the other of said blocks for forcing said blocks against said'impaling-pins.
